Keyboard operation on application launch

ABSTRACT

Methods and devices for selectively presenting a virtual keyboard are provided. More particularly, upon the receipt of instructions to launch an application, a determination can be made as to whether the application is associated with instructions to receive keyboard focus on launch. If the application is to receive keyboard focus on launch, a virtual keyboard is presented together with the newly launched application. Where an application is not set to receive keyboard focus on launch, a virtual keyboard that is presented when instructions to launch the application are received can be dismissed.

CROSS REFERENCE TO RELATED APPLICATION

The present application claims the benefits of and priority, under 35U.S.C. §119(e), to U.S. Provisional Application Ser. Nos. 61/389,000,filed Oct. 1, 2010, entitled “DUAL DISPLAY WINDOWING SYSTEM;”61/389,117, filed Oct. 1, 2010, entitled “MULTI-OPERATING SYSTEMPORTABLE DOCKETING DEVICE;” 61/389,087, filed Oct. 1, 2010, entitled“TABLET COMPUTING USER INTERFACE;”61/458,150, filed Nov. 17, 2010,entitled “Dual Screen Email Client;” ______, filed Sep. ______, 2011,entitled “MOBILE DEVICE.” Each of the aforementioned documents isincorporated herein by this reference in their entirety for all thatthey teach and for all purposes.

BACKGROUND

A substantial number of handheld computing devices, such as cellularphones, tablets, and E-Readers, make use of a touch screen display notonly to deliver display information to the user but also to receiveinputs from user interface commands. While touch screen displays mayincrease the configurability of the handheld device and provide a widevariety of user interface options, this flexibility typically comes at aprice. The dual use of the touch screen to provide content and receiveuser commands, while flexible for the user, may obfuscate the displayand cause visual clutter, thereby leading to user frustration and lossof productivity.

The small form factor of handheld computing devices requires a carefulbalancing between the displayed graphics and the area provided forreceiving inputs. On the one hand, the small display constrains thedisplay space, which may increase the difficulty of interpreting actionsor results. On the other, a virtual keypad or other user interfacescheme is superimposed on or positioned adjacent to an executingapplication, requiring the application to be squeezed into an evensmaller portion of the display.

This balancing act is particularly difficult for single display touchscreen devices. Single display touch screen devices are crippled bytheir limited screen space. When users are entering information into thedevice, through the single display, the ability to interpret informationin the display can be severely hampered, particularly when a complexinteraction between display and interface is required.

SUMMARY

There is a need for a dual multi-display handheld computing device thatprovides for enhanced power and/or versatility compared to conventionalsingle display handheld computing devices. These and other needs areaddressed by the various aspects, embodiments, and/or configurations ofthe present disclosure. Also, while the disclosure is presented in termsof exemplary embodiments, it should be appreciated that individualaspects of the disclosure can be separately claimed.

In some embodiments, a method for providing a virtual keyboard isprovided, the method comprising:

-   -   providing a device having first and second screens;    -   receiving an instruction to launch a first application;    -   determining whether the first application is set to receive a        keyboard focus upon launch; one of:        -   presenting a virtual keyboard after determining that the            first application is set to receive a keyboard focus upon            launch; and        -   not presenting a virtual keyboard after determining that the            first application is not set to receive a keyboard focus            upon launch.    -   In some embodiments, a device is provided, the device        comprising:    -   at least a first screen, the first screen including a touch        sensitive display area;    -   memory;    -   a processor;

application programming stored in the memory and executed by theprocessor, wherein the application programming is operable to:

-   -   receive an instruction to launch a first application;    -   determine whether the first application is to have keyboard        focus on launch of the first application;    -   present a virtual keyboard in response to determining that the        first application is to have keyboard focus of a user on launch        of the first application.

In some embodiments, a computer readable medium having stored thereoncomputer executable instructions, the computer executable instructionscausing a processor to execute a method for providing a virtualkeyboard, the computer executable instructions comprising:

instructions to receive a command to launch a first application;instructions to determine whether the first application is to receive akeyboard focus on launch of the first application;

at least one of:

-   -   instructions to display a virtual keyboard on launch in response        to determining that the first application is to receive a        keyboard focus on launch of the first application;    -   instructions to not display a virtual keyboard on launch in        response to determining that the first application is not to        receive a keyboard focus on launch of the first application.

The present disclosure can provide a number of advantages depending onthe particular aspect, embodiment, and/or configuration. Specifically,embodiments of the disclosed invention selectively provide a virtualkeyboard, depending on whether an application being launched is set toreceive a keyboard focus on launch. As a result, a virtual keyboard thatis presented in connection with a previously active application can bediscontinued, where an application being launched is not required. Inaddition, the launch of an application can be associated with thepresentation of a virtual keyboard, removing the need for a user toseparately access or call up the virtual keyboard. In addition, where avirtual keyboard is presented in connection with a previously activeapplication and a launched application is set to receive keyboard focus,presentation of the virtual keyboard can be continued upon launch of theapplication.

These and other advantages will be apparent from the disclosure.

The phrases “at least one”, “one or more”, and “and/or” are open-endedexpressions that are both conjunctive and disjunctive in operation. Forexample, each of the expressions “at least one of A, B and C”, “at leastone of A, B, or C”, “one or more of A, B, and C”, “one or more of A, B,or C” and “A, B, and/or C” means A alone, B alone, C alone, A and Btogether, A and C together, B and C together, or A, B and C together.

The term “a” or “an” entity refers to one or more of that entity. Assuch, the terms “a” (or “an”), “one or more” and “at least one” can beused interchangeably herein. It is also to be noted that the terms“comprising”, “including”, and “having” can be used interchangeably.

The term “automatic” and variations thereof, as used herein, refers toany process or operation done without material human input when theprocess or operation is performed. However, a process or operation canbe automatic, even though performance of the process or operation usesmaterial or immaterial human input, if the input is received beforeperformance of the process or operation. Human input is deemed to bematerial if such input influences how the process or operation will beperformed. Human input that consents to the performance of the processor operation is not deemed to be “material”.

The term “computer-readable medium” as used herein refers to anytangible storage and/or transmission medium that participate inproviding instructions to a processor for execution. Such a medium maytake many forms, including but not limited to, non-volatile media,volatile media, and transmission media. Non-volatile media includes, forexample, NVRAM, or magnetic or optical disks. Volatile media includesdynamic memory, such as main memory. Common forms of computer-readablemedia include, for example, a floppy disk, a flexible disk, hard disk,magnetic tape, or any other magnetic medium, magneto-optical medium, aCD-ROM, any other optical medium, punch cards, paper tape, any otherphysical medium with patterns of holes, a RAM, a PROM, and EPROM, aFLASH-EPROM, a solid state medium like a memory card, any other memorychip or cartridge, a carrier wave as described hereinafter, or any othermedium from which a computer can read. A digital file attachment toe-mail or other self-contained information archive or set of archives isconsidered a distribution medium equivalent to a tangible storagemedium. When the computer-readable media is configured as a database, itis to be understood that the database may be any type of database, suchas relational, hierarchical, object-oriented, and/or the like.Accordingly, the disclosure is considered to include a tangible storagemedium or distribution medium and prior art-recognized equivalents andsuccessor media, in which the software implementations of the presentdisclosure are stored.

The term “desktop” refers to a metaphor used to portray systems. Adesktop is generally considered a “surface” that typically includespictures, called icons, widgets, folders, etc. that can activate showapplications, windows, cabinets, files, folders, documents, and othergraphical items. The icons are generally selectable to initiate a taskthrough user interface interaction to allow a user to executeapplications or conduct other operations.

The term “screen,” “touch screen,” or “touchscreen” refers to a physicalstructure that includes one or more hardware components that provide thedevice with the ability to render a user interface and/or receive userinput. A screen can encompass any combination of gesture capture region,a touch sensitive display, and/or a configurable area. The device canhave one or more physical screens embedded in the hardware. However ascreen may also include an external peripheral device that may beattached and detached from the device. In embodiments, multiple externaldevices may be attached to the device. Thus, in embodiments, the screencan enable the user to interact with the device by touching areas on thescreen and provides information to a user through a display. The touchscreen may sense user contact in a number of different ways, such as bya change in an electrical parameter (e.g., resistance or capacitance),acoustic wave variations, infrared radiation proximity detection, lightvariation detection, and the like. In a resistive touch screen, forexample, normally separated conductive and resistive metallic layers inthe screen pass an electrical current. When a user touches the screen,the two layers make contact in the contacted location, whereby a changein electrical field is noted and the coordinates of the contactedlocation calculated. In a capacitive touch screen, a capacitive layerstores electrical charge, which is discharged to the user upon contactwith the touch screen, causing a decrease in the charge of thecapacitive layer. The decrease is measured, and the contacted locationcoordinates determined. In a surface acoustic wave touch screen, anacoustic wave is transmitted through the screen, and the acoustic waveis disturbed by user contact. A receiving transducer detects the usercontact instance and determines the contacted location coordinates.

The term “display” refers to a portion of one or more screens used todisplay the output of a computer to a user. A display may be asingle-screen display or a multi-screen display, referred to as acomposite display. A composite display can encompass the touch sensitivedisplay of one or more screens. A single physical screen can includemultiple displays that are managed as separate logical displays. Thus,different content can be displayed on the separate displays althoughpart of the same physical screen.

The term “displayed image” refers to an image produced on the display. Atypical displayed image is a window or desktop. The displayed image mayoccupy all or a portion of the display.

The term “display orientation” refers to the way in which a rectangulardisplay is oriented by a user for viewing. The two most common types ofdisplay orientation are portrait and landscape. In landscape mode, thedisplay is oriented such that the width of the display is greater thanthe height of the display (such as a 4:3 ratio, which is 4 units wideand 3 units tall, or a 16:9 ratio, which is 16 units wide and 9 unitstall). Stated differently, the longer dimension of the display isoriented substantially horizontal in landscape mode while the shorterdimension of the display is oriented substantially vertical. In theportrait mode, by contrast, the display is oriented such that the widthof the display is less than the height of the display. Stateddifferently, the shorter dimension of the display is orientedsubstantially horizontal in the portrait mode while the longer dimensionof the display is oriented substantially vertical.

The term “composited display” refers to a logical structure that definesa display that can encompass one or more screens. A multi-screen displaycan be associated with a composite display that encompasses all thescreens. The composite display can have different displaycharacteristics based on the various orientations of the device.

The term “gesture” refers to a user action that expresses an intendedidea, action, meaning, result, and/or outcome. The user action caninclude manipulating a device (e.g., opening or closing a device,changing a device orientation, moving a trackball or wheel, etc.),movement of a body part in relation to the device, movement of animplement or tool in relation to the device, audio inputs, etc. Agesture may be made on a device (such as on the screen) or with thedevice to interact with the device.

The term “module” as used herein refers to any known or later developedhardware, software, firmware, artificial intelligence, fuzzy logic, orcombination of hardware and software that is capable of performing thefunctionality associated with that element.

The term “gesture capture” refers to a sense or otherwise a detection ofan instance and/or type of user gesture. The gesture capture can occurin one or more areas of the screen, A gesture region can be on thedisplay, where it may be referred to as a touch sensitive display or offthe display where it may be referred to as a gesture capture area.

A “multi-screen application” refers to an application that is capable ofmultiple modes. The multi-screen application mode can include, but isnot limited to, a single screen mode (where the application is displayedon a single screen) or a composite display mode (where the applicationis displayed on two or more screens). A multi-screen application canhave different layouts optimized for the mode. Thus, the multi-screenapplication can have different layouts for a single screen or for acomposite display that can encompass two or more screens. The differentlayouts may have different screen/display dimensions and/orconfigurations on which the user interfaces of the multi-screenapplications can be rendered. The different layouts allow theapplication to optimize the application's user interface for the type ofdisplay, e.g., single screen or multiple screens. In single screen mode,the multi-screen application may present one window pane of information.In a composite display mode, the multi-screen application may presentmultiple window panes of information or may provide a larger and aricher presentation because there is more space for the displaycontents. The multi-screen applications may be designed to adaptdynamically to changes in the device and the mode depending on whichdisplay (single or composite) the system assigns to the multi-screenapplication. In alternative embodiments, the user can use a gesture torequest the application transition to a different mode, and, if adisplay is available for the requested mode, the device can allow theapplication to move to that display and transition modes.

A “single-screen application” refers to an application that is capableof single screen mode. Thus, the single-screen application can produceonly one window and may not be capable of different modes or differentdisplay dimensions. A single-screen application is incapable of theseveral modes discussed with the multi-screen application.

The term “window” refers to a, typically rectangular, displayed image onat least part of a display that contains or provides content differentfrom the rest of the screen. The window may obscure the desktop.

The terms “determine”, “calculate” and “compute,” and variationsthereof, as used herein, are used interchangeably and include any typeof methodology, process, mathematical operation or technique.

It shall be understood that the term “means” as used herein shall begiven its broadest possible interpretation in accordance with 35 U.S.C.,Section 112, Paragraph 6. Accordingly, a claim incorporating the term“means” shall cover all structures, materials, or acts set forth herein,and all of the equivalents thereof.

DETAILED DESCRIPTION

Presented herein are embodiments of a device. The device can be acommunications device, such as a cellular telephone, or other smartdevice. The device can include two screens that are oriented to provideseveral unique display configurations. Further, the device can receiveuser input in unique ways. The overall design and functionality of thedevice provides for an enhanced user experience making the device moreuseful and more efficient.

Mechanical Features:

FIGS. 1A-1J illustrate a device 100 in accordance with embodiments ofthe present disclosure. As described in greater detail below, device 100can be positioned in a number of different ways each of which providesdifferent functionality to a user. The device 100 is a multi-screendevice that includes a primary screen 104 and a secondary screen 108,both of which are touch sensitive. In embodiments, the entire frontsurface of screens 104 and 108 may be touch sensitive and capable ofreceiving input by a user touching the front surface of the screens 104and 108. Primary screen 104 includes touch sensitive display 110, which,in addition to being touch sensitive, also displays information to auser. Secondary screen 108 includes touch sensitive display 114, whichalso displays information to a user. In other embodiments, screens 104and 108 may include more than one display area.

Primary screen 104 also includes a configurable area 112 that has beenconfigured for specific inputs when the user touches portions of theconfigurable area 112. Secondary screen 108 also includes a configurablearea 116 that has been configured for specific inputs. Areas 112 a and116 a have been configured to receive a “back” input indicating that auser would like to view information previously displayed. Areas 112 band 116 b have been configured to receive a “menu” input indicating thatthe user would like to view options from a menu. Areas 112 c and 116 chave been configured to receive a “home” input indicating that the userwould like to view information associated with a “home” view. In otherembodiments, areas 112 a-c and 116 a-c may be configured, in addition tothe configurations described above, for other types of specific inputsincluding controlling features of device 100, some non-limiting examplesincluding adjusting overall system power, adjusting the volume,adjusting the brightness, adjusting the vibration, selecting ofdisplayed items (on either of screen 104 or 108), operating a camera,operating a microphone, and initiating/terminating of telephone calls.Also, in some embodiments, areas 112 a-C and 116 a-C may be configuredfor specific inputs depending upon the application running on device 100and/or information displayed on touch sensitive displays 110 and/or 114.

In addition to touch sensing, primary screen 104 and secondary screen108 may also include areas that receive input from a user withoutrequiring the user to touch the display area of the screen. For example,primary screen 104 includes gesture capture area 120, and secondaryscreen 108 includes gesture capture area 124. These areas are able toreceive input by recognizing gestures made by a user without the needfor the user to actually touch the surface of the display area. Incomparison to touch sensitive displays 110 and 114, the gesture captureareas 120 and 124 are commonly not capable of rendering a displayedimage.

The two screens 104 and 108 are connected together with a hinge 128,shown clearly in FIG. 1C (illustrating a back view of device 100). Hinge128, in the embodiment shown in FIGS. 1A-1J, is a center hinge thatconnects screens 104 and 108 so that when the hinge is closed, screens104 and 108 are juxtaposed (i.e., side-by-side) as shown in FIG. 1B(illustrating a front view of device 100). Hinge 128 can be opened toposition the two screens 104 and 108 in different relative positions toeach other. As described in greater detail below, the device 100 mayhave different functionalities depending on the relative positions ofscreens 104 and 108.

FIG. 1D illustrates the right side of device 100. As shown in FIG. 1D,secondary screen 108 also includes a card slot 132 and a port 136 on itsside. Card slot 132 in embodiments, accommodates different types ofcards including a subscriber identity module (SIM). Port 136 inembodiments is an input/output port (I/O port) that allows device 100 tobe connected to other peripheral devices, such as a display, keyboard,or printing device. As can be appreciated, these are merely someexamples and in other embodiments device 100 may include other slots andports such as slots and ports for accommodating additional memorydevices and/or for connecting other peripheral devices. Also shown inFIG. 1D is an audio jack 140 that accommodates a tip, ring, sleeve (TRS)connector for example to allow a user to utilize headphones or aheadset.

Device 100 also includes a number of buttons 158. For example, FIG. 1Eillustrates the left side of device 100. As shown in FIG. 1E, the sideof primary screen 104 includes three buttons 144, 148, and 152, whichcan be configured for specific inputs. For example, buttons 144, 148,and 152 may be configured to, in combination or alone, control a numberof aspects of device 100. Some non-limiting examples include overallsystem power, volume, brightness, vibration, selection of displayeditems (on either of screen 104 or 108), a camera, a microphone, andinitiation/termination of telephone calls. In some embodiments, insteadof separate buttons two buttons may be combined into a rocker button.This arrangement is useful in situations where the buttons areconfigured to control features such as volume or brightness. In additionto buttons 144, 148, and 152, device 100 also includes a button 156,shown in FIG. 1F, which illustrates the top of device 100. In oneembodiment, button 156 is configured as an on/off button used to controloverall system power to device 100. In other embodiments, button 156 isconfigured to, in addition to or in lieu of controlling system power,control other aspects of device 100. In some embodiments, one or more ofthe buttons 144, 148, 152, and 156 are capable of supporting differentuser commands. By way of example, a normal press has a duration commonlyof less than about 1 second and resembles a quick tap. A medium presshas a duration commonly of 1 second or more but less than about 12seconds. A long press has a duration commonly of about 12 seconds ormore. The function of the buttons is normally specific to theapplication that is currently in focus on the respective display 110 and114. In a telephone application for instance and depending on theparticular button, a normal, medium, or long press can mean end call,increase in call volume, decrease in call volume, and toggle microphonemute. In a camera or video application for instance and depending on theparticular button, a normal, medium, or long press can mean increasezoom, decrease zoom, and take photograph or record video.

There are also a number of hardware components within device 100. Asillustrated in FIG. 1C, device 100 includes a speaker 160 and amicrophone 164. Device 100 also includes a camera 168 (FIG. 1B).Additionally, device 100 includes two position sensors 172A and 172B,which are used to determine the relative positions of screens 104 and108. In one embodiment, position sensors 172A and 172B are Hall effectsensors. However, in other embodiments other sensors can be used inaddition to or in lieu of the Hall effect sensors. An accelerometer 176may also be included as part of device 100 to determine the orientationof the device 100 and/or the orientation of screens 104 and 108.Additional internal hardware components that may be included in device100 are described below with respect to FIG. 2.

The overall design of device 100 allows it to provide additionalfunctionality not available in other communication devices. Some of thefunctionality is based on the various positions and orientations thatdevice 100 can have. As shown in FIGS. 1B-1G, device 100 can be operatedin an “open” position where screens 104 and 108 are juxtaposed. Thisposition allows a large display area for displaying information to auser. When position sensors 172A and 172B determine that device 100 isin the open position, they can generate a signal that can be used totrigger different events such as displaying information on both screens104 and 108. Additional events may be triggered if accelerometer 176determines that device 100 is in a portrait position (FIG. 1B) asopposed to a landscape position (not shown).

In addition to the open position, device 100 may also have a “closed”position illustrated in FIG. 1H. Again, position sensors 172A and 172Bcan generate a signal indicating that device 100 is in the “closed”position. This can trigger an event that results in a change ofdisplayed information on screen 104 and/or 108. For example, device 100may be programmed to stop displaying information on one of the screens,e.g., screen 108, since a user can only view one screen at a time whendevice 100 is in the “closed” position. In other embodiments, the signalgenerated by position sensors 172A and 172B, indicating that the device100 is in the “closed” position, can trigger device 100 to answer anincoming telephone call. The “closed” position can also be a preferredposition for utilizing the device 100 as a mobile phone.

Device 100 can also be used in an “easel” position which is illustratedin FIG. 1I. In the “easel” position, screens 104 and 108 are angled withrespect to each other and facing outward with the edges of screens 104and 108 substantially horizontal. In this position, device 100 can beconfigured to display information on both screens 104 and 108 to allowtwo users to simultaneously interact with device 100. When device 100 isin the “easel” position, sensors 172A and 172B generate a signalindicating that the screens 104 and 108 are positioned at an angle toeach other, and the accelerometer 176 can generate a signal indicatingthat device 100 has been placed so that the edge of screens 104 and 108are substantially horizontal. The signals can then be used incombination to generate events that trigger changes in the display ofinformation on screens 104 and 108.

FIG. 1J illustrates device 100 in a “modified easel” position. In the“modified easel” position, one of screens 104 or 108 is used as a standand is faced down on the surface of an object such as a table. Thisposition provides a convenient way for information to be displayed to auser in landscape orientation. Similar to the easel position, whendevice 100 is in the “modified easel” position, position sensors 172Aand 172B generate a signal indicating that the screens 104 and 108 arepositioned at an angle to each other. The accelerometer 176 wouldgenerate a signal indicating that device 100 has been positioned so thatone of screens 104 and 108 is faced downwardly and is substantiallyhorizontal. The signals can then be used to generate events that triggerchanges in the display of information of screens 104 and 108. Forexample, information may not be displayed on the screen that is facedown since a user cannot see the screen.

Transitional states are also possible. When the position sensors 172Aand B and/or accelerometer indicate that the screens are being closed orfolded (from open), a closing transitional state is recognized.Conversely when the position sensors 172A and B indicate that thescreens are being opened or folded (from closed), an openingtransitional state is recognized. The closing and opening transitionalstates are typically time-based, or have a maximum time duration from asensed starting point. Normally, no user input is possible when one ofthe closing and opening states is in effect. In this manner, incidentaluser contact with a screen during the closing or opening function is notmisinterpreted as user input. In embodiments, another transitional stateis possible when the device 100 is closed. This additional transitionalstate allows the display to switch from one screen 104 to the secondscreen 108 when the device 100 is closed based on some user input, e.g.,a double tap on the screen 110,114.

Device State:

FIGS. 3A and 3B represent illustrative states of device 100. While anumber of illustrative states are shown, and transitions from a firststate to a second state, it is to be appreciated that the illustrativestate diagram may not encompass all possible states and/or all possibletransitions from a first state to a second state. As illustrated in FIG.3, the various arrows between the states (illustrated by the staterepresented in the circle) represent a physical change that occurs tothe device 100, that is detected by one or more of hardware andsoftware, the detection triggering one or more of a hardware and/orsoftware interrupt that is used to control and/or manage one or morefunctions of device 100.

As illustrated in FIG. 3A, there are twelve exemplary “physical” states:closed 304, transition 308 (or opening transitional state), easel 312,modified easel 316, open 320, inbound/outbound call or communication324, image/video capture 328, transition 332 (or closing transitionalstate), landscape 340, docked 336, docked 344 and landscape 348. Next toeach illustrative state is a representation of the physical state of thedevice 100 with the exception of states 324 and 328, where the state isgenerally symbolized by the international icon for a telephone and theicon for a camera, respectfully.

In state 304, the device is in a closed state with the device 100generally oriented in the portrait direction with the primary screen 104and the secondary screen 108 back-to-back in different planes (see FIG.1H). From the closed state, the device 100 can enter, for example,docked state 336, where the device 100 is coupled with a dockingstation, docking cable, or in general docked or associated with one ormore other devices or peripherals, or the landscape state 340, where thedevice 100 is generally oriented with the primary screen 104 facing theuser, and the primary screen 104 and the secondary screen 108 beingback-to-back.

In the closed state, the device can also move to a transitional statewhere the device remains closed but the display is moved from one screen104 to another screen 108 based on a user input, e.g., a double tap onthe screen 110, 114. Still another embodiment includes a bilateralstate. In the bilateral state, the device remains closed, but a singleapplication displays at least one window on both the first display 110and the second display 114. The windows shown on the first and seconddisplay 110, 114 may be the same or different based on the applicationand the state of that application. For example, while acquiring an imagewith a camera, the device may display the view finder on the firstdisplay 110 and displays a preview for the photo subjects (full screenand mirrored left-to-right) on the second display 114.

In state 308, a transition state from the closed state 304 to thesemi-open state or easel state 312, the device 100 is shown opening withthe primary screen 104 and the secondary screen 108 being rotated arounda point of axis coincidence with the hinge. Upon entering the easelstate 312, the primary screen 104 and the secondary screen 108 areseparated from one another such that, for example, the device 100 cansit in an easel-like configuration on a surface.

In state 316, known as the modified easel position, the device 100 hasthe primary screen 104 and the secondary screen 108 in a similarrelative relationship to one another as in the easel state 312, with thedifference being one of the primary screen 104 or the secondary screen108 are placed on a surface as shown.

State 320 is the open state where the primary screen 104 and thesecondary screen 108 are generally on the same plane. From the openstate, the device 100 can transition to the docked state 344 or the openlandscape state 348. In the open state 320, the primary screen 104 andthe secondary screen 108 are generally in the portrait-like orientationwhile in landscaped state 348 the primary screen 104 and the secondaryscreen 108 are generally in a landscape-like orientation.

State 324 is illustrative of a communication state, such as when aninbound or outbound call is being received or placed, respectively, bythe device 100. While not illustrated for clarity, it should beappreciated the device 100 can transition to the inbound/outbound callstate 324 from any state illustrated in FIG. 3. In a similar manner, theimage/video capture state 328 can be entered into from any other statein FIG. 3, with the image/video capture state 328 allowing the device100 to take one or more images via a camera and/or videos with a videocapture device 240.

Transition state 322 illustratively shows primary screen 104 and thesecondary screen 108 being closed upon one another for entry into, forexample, the closed state 304.

FIG. 3B illustrates, with reference to the key, the inputs that arereceived to detect a transition from a first state to a second state. InFIG. 3B, various combinations of states are shown with in general, aportion of the columns being directed toward a portrait state 352, alandscape state 356, and a portion of the rows being directed toportrait state 360 and landscape state 364.

In FIG. 3B, the Key indicates that “H” represents an input from one ormore Hall Effect sensors, “A” represents an input from one or moreaccelerometers, “T” represents an input from a timer, “P” represents acommunications trigger input and “I” represents an image and/or videocapture request input. Thus, in the center portion 376 of the chart, aninput, or combination of inputs, are shown that represent how the device100 detects a transition from a first physical state to a secondphysical state.

As discussed, in the center portion of the chart 376, the inputs thatare received enable the detection of a transition from, for example, aportrait open state to a landscape easel state—shown in bold—“HAT.” Forthis exemplary transition from the portrait open to the landscape easelstate, a Hall Effect sensor (“H”), an accelerometer (“A”) and a timer(“T”) input may be needed. The timer input can be derived from, forexample, a clock associated with the processor.

In addition to the portrait and landscape states, a docked state 368 isalso shown that is triggered based on the receipt of a docking signal372. As discussed above and in relation to FIG. 3, the docking signalcan be triggered by the association of the device 100 with one or moreother device 100 s, accessories, peripherals, smart docks, or the like.

User Interaction:

FIGS. 4A through 4H depict various graphical representations of gestureinputs that may be recognized by the screens 104, 108. The gestures maybe performed not only by a user's body part, such as a digit, but alsoby other devices, such as a stylus, that may be sensed by the contactsensing portion(s) of a screen 104, 108. In general, gestures areinterpreted differently, based on where the gestures are performed(either directly on the display 110, 114 or in the gesture captureregion 120, 124). For example, gestures in the display 110,114 may bedirected to a desktop or application, and gestures in the gesturecapture region 120, 124 may be interpreted as for the system.

With reference to FIGS. 4A-4H, a first type of gesture, a touch gesture420, is substantially stationary on the screen 104,108 for a selectedlength of time. A circle 428 represents a touch or other contact typereceived at particular location of a contact sensing portion of thescreen. The circle 428 may include a border 432, the thickness of whichindicates a length of time that the contact is held substantiallystationary at the contact location. For instance, a tap 420 (or shortpress) has a thinner border 432 a than the border 432 b for a long press424 (or for a normal press). The long press 424 may involve a contactthat remains substantially stationary on the screen for longer timeperiod than that of a tap 420. As will be appreciated, differentlydefined gestures may be registered depending upon the length of timethat the touch remains stationary prior to contact cessation or movementon the screen.

With reference to FIG. 4C, a drag gesture 400 on the screen 104,108 isan initial contact (represented by circle 428) with contact movement 436in a selected direction. The initial contact 428 may remain stationaryon the screen 104,108 for a certain amount of time represented by theborder 432. The drag gesture typically requires the user to contact anicon, window, or other displayed image at a first location followed bymovement of the contact in a drag direction to a new second locationdesired for the selected displayed image. The contact movement need notbe in a straight line but have any path of movement so long as thecontact is substantially continuous from the first to the secondlocations.

With reference to FIG. 4D, a flick gesture 404 on the screen 104,108 isan initial contact (represented by circle 428) with truncated contactmovement 436 (relative to a drag gesture) in a selected direction. Inembodiments, a flick has a higher exit velocity for the last movement inthe gesture compared to the drag gesture. The flick gesture can, forinstance, be a finger snap following initial contact. Compared to a draggesture, a flick gesture generally does not require continual contactwith the screen 104,108 from the first location of a displayed image toa predetermined second location. The contacted displayed image is movedby the flick gesture in the direction of the flick gesture to thepredetermined second location. Although both gestures commonly can movea displayed image from a first location to a second location, thetemporal duration and distance of travel of the contact on the screen isgenerally less for a flick than for a drag gesture.

With reference to FIG. 4E, a pinch gesture 408 on the screen 104,108 isdepicted. The pinch gesture 408 may be initiated by a first contact 428to the screen 104,108 by, for example, a first digit and a secondcontact 428 b to the screen 104,108 by, for example, a second digit. Thefirst and second contacts 428 a,b may be detected by a common contactsensing portion of a common screen 104,108, by different contact sensingportions of a common screen 104 or 108, or by different contact sensingportions of different screens. The first contact 428 a is held for afirst amount of time, as represented by the border 432 a, and the secondcontact 428 b is held for a second amount of time, as represented by theborder 432 b. The first and second amounts of time are generallysubstantially the same, and the first and second contacts 428 a, bgenerally occur substantially simultaneously. The first and secondcontacts 428 a, b generally also include corresponding first and secondcontact movements 436 a, b, respectively. The first and second contactmovements 436 a, b are generally in opposing directions. Stated anotherway, the first contact movement 436 a is towards the second contact 436b, and the second contact movement 436 b is towards the first contact436 a. More simply stated, the pinch gesture 408 may be accomplished bya user's digits touching the screen 104,108 in a pinching motion.

With reference to FIG. 4F, a spread gesture 410 on the screen 104,108 isdepicted. The spread gesture 410 may be initiated by a first contact 428a to the screen 104,108 by, for example, a first digit and a secondcontact 428 b to the screen 104,108 by, for example, a second digit. Thefirst and second contacts 428 a,b may be detected by a common contactsensing portion of a common screen 104,108, by different contact sensingportions of a common screen 104,108, or by different contact sensingportions of different screens. The first contact 428 a is held for afirst amount of time, as represented by the border 432 a, and the secondcontact 428 b is held for a second amount of time, as represented by theborder 432 b. The first and second amounts of time are generallysubstantially the same, and the first and second contacts 428 a, bgenerally occur substantially simultaneously. The first and secondcontacts 428 a, b generally also include corresponding first and secondcontact movements 436 a, b, respectively. The first and second contactmovements 436 a, b are generally in a common direction. Stated anotherway, the first and second contact movements 436 a, b are away from thefirst and second contacts 428 a, b. More simply stated, the spreadgesture 410 may be accomplished by a user's digits touching the screen104,108 in a spreading motion.

The above gestures may be combined in any manner, such as those shown byFIGS. 4G and 4H, to produce a determined functional result. For example,in FIG. 4G a tap gesture 420 is combined with a drag or flick gesture412 in a direction away from the tap gesture 420. In FIG. 4H, a tapgesture 420 is combined with a drag or flick gesture 412 in a directiontowards the tap gesture 420.

The functional result of receiving a gesture can vary depending on anumber of factors, including a state of the device 100, display 110,114, or screen 104, 108, a context associated with the gesture, orsensed location of the gesture. The state of the device commonly refersto one or more of a configuration of the device 100, a displayorientation, and user and other inputs received by the device 100.Context commonly refers to one or more of the particular application(s)selected by the gesture and the portion(s) of the application currentlyexecuting, whether the application is a single- or multi-screenapplication, and whether the application is a multi-screen applicationdisplaying one or more windows in one or more screens or in one or morestacks. Sensed location of the gesture commonly refers to whether thesensed set(s) of gesture location coordinates are on a touch sensitivedisplay 110, 114 or a gesture capture region 120, 124, whether thesensed set(s) of gesture location coordinates are associated with acommon or different display or screen 104,108, and/or what portion ofthe gesture capture region contains the sensed set(s) of gesturelocation coordinates.

A tap, when received by an a touch sensitive display 110, 114, can beused, for instance, to select an icon to initiate or terminate executionof a corresponding application, to maximize or minimize a window, toreorder windows in a stack, and to provide user input such as bykeyboard display or other displayed image. A drag, when received by atouch sensitive display 110, 114, can be used, for instance, to relocatean icon or window to a desired location within a display, to reorder astack on a display, or to span both displays (such that the selectedwindow occupies a portion of each display simultaneously). A flick, whenreceived by a touch sensitive display 110, 114 or a gesture captureregion 120, 124, can be used to relocate a window from a first displayto a second display or to span both displays (such that the selectedwindow occupies a portion of each display simultaneously). Unlike thedrag gesture, however, the flick gesture is generally not used to movethe displayed image to a specific user-selected location but to adefault location that is not configurable by the user.

The pinch gesture, when received by a touch sensitive display 110, 114or a gesture capture region 120, 124, can be used to minimize orotherwise increase the displayed area or size of a window (typicallywhen received entirely by a common display), to switch windows displayedat the top of the stack on each display to the top of the stack of theother display (typically when received by different displays orscreens), or to display an application manager (a “pop-up window” thatdisplays the windows in the stack). The spread gesture, when received bya touch sensitive display 110, 114 or a gesture capture region 120, 124,can be used to maximize or otherwise decrease the displayed area or sizeof a window, to switch windows displayed at the top of the stack on eachdisplay to the top of the stack of the other display (typically whenreceived by different displays or screens), or to display an applicationmanager (typically when received by an off-screen gesture capture regionon the same or different screens).

The combined gestures of FIG. 4G, when received by a common displaycapture region in a common display or screen 104,108, can be used tohold a first window stack location in a first stack constant for adisplay receiving the gesture while reordering a second window stacklocation in a second window stack to include a window in the displayreceiving the gesture. The combined gestures of FIG. 4H, when receivedby different display capture regions in a common display or screen104,108 or in different displays or screens, can be used to hold a firstwindow stack location in a first window stack constant for a displayreceiving the tap part of the gesture while reordering a second windowstack location in a second window stack to include a window in thedisplay receiving the flick or drag gesture. Although specific gesturesand gesture capture regions in the preceding examples have beenassociated with corresponding sets of functional results, it is to beappreciated that these associations can be redefined in any manner toproduce differing associations between gestures and/or gesture captureregions and/or functional results.

Firmware and Software:

The memory 508 may store and the processor 504 may execute one or moresoftware components. These components can include at least one operatingsystem (OS) 516, an application manager 562, a desktop 566, and/or oneor more applications 564 a and/or 564 b from an application store 560.The OS 516 can include a framework 520, one or more frame buffers 548,one or more drivers 512, previously described in conjunction with FIG.2, and/or a kernel 518. The OS 516 can be any software, consisting ofprograms and data, which manages computer hardware resources andprovides common services for the execution of various applications 564.The OS 516 can be any operating system and, at least in someembodiments, dedicated to mobile devices, including, but not limited to,Linux, ANDROID™, iPhone OS (IOS™), WINDOWS PHONE 7™, etc. The OS 516 isoperable to provide functionality to the phone by executing one or moreoperations, as described herein.

The applications 564 can be any higher level software that executesparticular functionality for the user. Applications 564 can includeprograms such as email clients, web browsers, texting applications,games, media players, office suites, etc. The applications 564 can bestored in an application store 560, which may represent any memory ordata storage, and the management software associated therewith, forstoring the applications 564. Once executed, the applications 564 may berun in a different area of memory 508.

The framework 520 may be any software or data that allows the multipletasks running on the device to interact. In embodiments, at leastportions of the framework 520 and the discrete components describedhereinafter may be considered part of the OS 516 or an application 564.However, these portions will be described as part of the framework 520,but those components are not so limited. The framework 520 can include,but is not limited to, a Multi-Display Management (MDM) module 524, aSurface Cache module 528, a Window Management module 532, an InputManagement module 536, a Task Management module 540, an ApplicationModel Manager 542, a Display Controller, one or more frame buffers 548,a task stack 552, one or more window stacks 550 (which is a logicalarrangement of windows and/or desktops in a display area), and/or anevent buffer 556.

The MDM module 524 includes one or more modules that are operable tomanage the display of applications or other data on the screens of thedevice. An embodiment of the MDM module 524 is described in conjunctionwith FIG. 5B. In embodiments, the MDM module 524 receives inputs fromthe other OS 516 components, such as, the drivers 512, and from theapplications 564 to determine continually the state of the device 100.The inputs assist the MDM module 524 in determining how to configure andallocate the displays according to the application's preferences andrequirements, and the user's actions. Once a determination for displayconfigurations is made, the MDM module 524 can bind the applications 564to a display. The configuration may then be provided to one or moreother components to generate a window with a display.

The Surface Cache module 528 includes any memory or storage and thesoftware associated therewith to store or cache one or more images ofwindows. A series of active and/or non-active windows (or other displayobjects, such as, a desktop display) can be associated with eachdisplay. An active window (or other display object) is currentlydisplayed. A non-active windows (or other display objects) were openedand, at some time, displayed but are now not displayed. To enhance theuser experience, before a window transitions from an active state to aninactive state, a “screen shot” of a last generated image of the window(or other display object) can be stored. The Surface Cache module 528may be operable to store a bitmap of the last active image of a window(or other display object) not currently displayed. Thus, the SurfaceCache module 528 stores the images of non-active windows (or otherdisplay objects) in a data store.

In embodiments, the Window Management module 532 is operable to managethe windows (or other display objects) that are active or not active oneach of the displays. The Window Management module 532, based oninformation from the MDM module 524, the OS 516, or other components,determines when a window (or other display object) is visible or notactive. The Window Management module 532 may then put a non-visiblewindow (or other display object) in a “not active state” and, inconjunction with the Task Management module Task Management 540 suspendsthe application's operation. Further, the Window Management module 532may assign, through collaborative interaction with the MDM module 524, adisplay identifier to the window (or other display object) or manage oneor more other items of data associated with the window (or other displayobject). The Window Management module 532 may also provide the storedinformation to the application 564, the Task Management module 540, orother components interacting with or associated with the window (orother display object). The Window Management module 532 can alsoassociate an input task with a window based on window focus and displaycoordinates within the motion space.

The Input Management module 536 is operable to manage events that occurwith the device. An event is any input into the window environment, forexample, a user interface interactions with a user. The Input Managementmodule 536 receives the events and logically stores the events in anevent buffer 556. Events can include such user interface interactions asa “down event,” which occurs when a screen 104, 108 receives a touchsignal from a user, a “move event,” which occurs when the screen 104,108 determines that a user's finger is moving across a screen(s), an “upevent, which occurs when the screen 104, 108 determines that the userhas stopped touching the screen 104, 108, etc. These events arereceived, stored, and forwarded to other modules by the Input Managementmodule 536. The Input Management module 536 may also map screen inputsto a motion space which is the culmination of all physical and virtualdisplay available on the device.

The motion space is a virtualized space that includes all touchsensitive displays 110,114 “tiled” together to mimic the physicaldimensions of the device 100. For example, when the device 100 isunfolded, the motion space size may be 960×800, which may be the numberof pixels in the combined display area for both touch sensitive displays110, 114. If a user touches on a first touch sensitive display 110 onlocation (40, 40), a full screen window can receive touch event withlocation (40, 40). If a user touches on a second touch sensitive display114, with location (40, 40), the full screen window can receive touchevent with location (520, 40), because the second touch sensitivedisplay 114 is on the right side of the first touch sensitive display110, so the device 100 can offset the touch by the first touch sensitivedisplay's 110 width, which is 480 pixels. When a hardware event occurswith location info from a driver 512, the framework 520 can up-scale thephysical location to the motion space because the location of the eventmay be different based on the device orientation and state. The motionspace may be as described in U.S. patent application Ser. No.13/187,026, filed Jul. 20, 2011, entitled “Systems and Methods forReceiving Gesture Inputs Spanning Multiple Input Devices,” which ishereby incorporated by reference in its entirety for all that it teachesand for all purposes.

A task can be an application and a sub-task can be an applicationcomponent that provides a window with which users can interact to dosomething, such as dial the phone, take a photo, send an email, or viewa map. Each task may be given a window in which to draw a userinterface. The window typically fills a display (for example, touchsensitive display 110,114), but may be smaller than the display 110,114and float on top of other windows. An application usually consists ofmultiple sub-tasks that are loosely bound to each other. Typically, onetask in an application is specified as the “main” task, which ispresented to the user when launching the application for the first time.Each task can then start another task or sub-task to perform differentactions.

The Task Management module 540 is operable to manage the operation ofone or more applications 564 that may be executed by the device. Thus,the Task Management module 540 can receive signals to launch, suspend,terminate, etc. an application or application sub-tasks stored in theapplication store 560. The Task Management module 540 may theninstantiate one or more tasks or sub-tasks of the application 564 tobegin operation of the application 564. Further, the Task ManagementModule 540 may launch, suspend, or terminate a task or sub-task as aresult of user input or as a result of a signal from a collaboratingframework 520 component. The Task Management Module 540 is responsiblefor managing the lifecycle of applications (tasks and sub-task) fromwhen the application is launched to when the application is terminated.

The processing of the Task Management Module 540 is facilitated by atask stack 552, which is a logical structure associated with the TaskManagement Module 540. The task stack 552 maintains the state of alltasks and sub-tasks on the device 100. When some component of theoperating system 516 requires a task or sub-task to transition in itslifecycle, the OS 516 component can notify the Task Management Module540. The Task Management Module 540 may then locate the task orsub-task, using identification information, in the task stack 552, andsend a signal to the task or sub-task indicating what kind of lifecycletransition the task needs to execute. Informing the task or sub-task ofthe transition allows the task or sub-task to prepare for the lifecyclestate transition. The Task Management Module 540 can then execute thestate transition for the task or sub-task. In embodiments, the statetransition may entail triggering the OS kernel 518 to terminate the taskwhen termination is required.

Further, the Task Management module 540 may suspend the application 564based on information from the Window Management Module 532. Suspendingthe application 564 may maintain application data in memory but maylimit or stop the application 564 from rendering a window or userinterface. Once the application becomes active again, the TaskManagement module 540 can again trigger the application to render itsuser interface. In embodiments, if a task is suspended, the task maysave the task's state in case the task is terminated. In the suspendedstate, the application task may not receive input because theapplication window is not visible to the user.

The frame buffer 548 is a logical structure(s) used to render the userinterface. The frame buffer 548 can be created and destroyed by the OSkernel 518. However, the Display Controller 544 can write the imagedata, for the visible windows, into the frame buffer 548. A frame buffer548 can be associated with one screen or multiple screens. Theassociation of a frame buffer 548 with a screen can be controlleddynamically by interaction with the OS kernel 518. A composite displaymay be created by associating multiple screens with a single framebuffer 548. Graphical data used to render an application's window userinterface may then be written to the single frame buffer 548, for thecomposite display, which is output to the multiple screens 104,108. TheDisplay Controller 544 can direct an application's user interface to aportion of the frame buffer 548 that is mapped to a particular display110,114, thus, displaying the user interface on only one screen 104 or108. The Display Controller 544 can extend the control over userinterfaces to multiple applications, controlling the user interfaces foras many displays as are associated with a frame buffer 548 or a portionthereof. This approach compensates for the multiple physical screens104,108 that are in use by the software component above the DisplayController 544.

The Application Manager 562 is an application that provides apresentation layer for the window environment. Thus, the ApplicationManager 562 provides the graphical model for rendering by the TaskManagement Module 540. Likewise, the Desktop 566 provides thepresentation layer for the Application Store 560. Thus, the desktopprovides a graphical model of a surface having selectable applicationicons for the Applications 564 in the Application Store 560 that can beprovided to the Window Management Module 556 for rendering.

Further, the framework can include an Application Model Manager (AMM)542. The Application Manager 562 may interface with the AMM 542. Inembodiments, the AMM 542 receives state change information from thedevice 100 regarding the state of applications (which are running orsuspended). The AMM 542 can associate bit map images from the SurfaceCache Module 528 to the tasks that are alive (running or suspended).Further, the AMM 542 can convert the logical window stack maintained inthe Task Manager Module 540 to a linear (“film strip” or “deck ofcards”) organization that the user perceives when the using the offgesture capture area 120 to sort through the windows. Further, the AMM542 may provide a list of executing applications to the ApplicationManager 562.

An embodiment of the MDM module 524 is shown in FIG. 5B. The MDM module524 is operable to determine the state of the environment for thedevice, including, but not limited to, the orientation of the device,whether the device 100 is opened or closed, what applications 564 areexecuting, how the applications 564 are to be displayed, what actionsthe user is conducting, the tasks being displayed, etc. To configure thedisplay, the MDM module 524 interprets these environmental factors anddetermines a display configuration, as described in conjunction withFIGS. 6A-6J. Then, the MDM module 524 can bind the applications 564 orother device components to the displays. The configuration may then besent to the Display Controller 544 and/or the other components withinthe OS 516 to generate the display. The MDM module 524 can include oneor more of, but is not limited to, a Display Configuration Module 568, aPreferences Module 572, a Device State Module 574, a Gesture Module 576,a Requirements Module 580, an Event Module 584, and/or a Binding Module588.

The Display Configuration Module 568 determines the layout for thedisplay. In embodiments, the Display Configuration Module 568 candetermine the environmental factors. The environmental factors may bereceived from one or more other MDM modules 524 or from other sources.The Display Configuration Module 568 can then determine from the list offactors the best configuration for the display. Some embodiments of thepossible configurations and the factors associated therewith aredescribed in conjunction with FIGS. 6A-6F.

The Preferences Module 572 is operable to determine display preferencesfor an application 564 or other component. For example, an applicationcan have a preference for Single or Dual displays. The PreferencesModule 572 can determine an application's display preference (e.g., byinspecting the application's preference settings) and may allow theapplication 564 to change to a mode (e.g., single screen, dual screen,max, etc.) if the device 100 is in a state that can accommodate thepreferred mode. However, some user interface policies may disallow amode even if the mode is available. As the configuration of the devicechanges, the preferences may be reviewed to determine if a betterdisplay configuration can be achieved for an application 564.

The Device State Module 574 is operable to determine or receive thestate of the device. The state of the device can be as described inconjunction with FIGS. 3A and 3B. The state of the device can be used bythe Display Configuration Module 568 to determine the configuration forthe display. As such, the Device State Module 574 may receive inputs andinterpret the state of the device. The state information is thenprovided to the Display Configuration Module 568.

The Gesture Module 576 is shown as part of the MDM module 524, but, inembodiments, the Gesture module 576 may be a separate Framework 520component that is separate from the MDM module 524. In embodiments, theGesture Module 576 is operable to determine if the user is conductingany actions on any part of the user interface. In alternativeembodiments, the Gesture Module 576 receives user interface actions fromthe configurable area 112,116 only. The Gesture Module 576 can receivetouch events that occur on the configurable area 112,116 (or possiblyother user interface areas) by way of the Input Management Module 536and may interpret the touch events (using direction, speed, distance,duration, and various other parameters) to determine what kind ofgesture the user is performing. When a gesture is interpreted, theGesture Module 576 can initiate the processing of the gesture and, bycollaborating with other Framework 520 components, can manage therequired window animation. The Gesture Module 576 collaborates with theApplication Model Manager 542 to collect state information with respectto which applications are running (active or paused) and the order inwhich applications must appear when a user gesture is performed. TheGesture Module 576 may also receive references to bitmaps (from theSurface Cache Module 528) and live windows so that when a gesture occursit can instruct the Display Controller 544 how to move the window(s)across the display 110,114. Thus, suspended applications may appear tobe running when those windows are moved across the display 110,114.

Further, the Gesture Module 576 can receive task information either fromthe Task Manage Module 540 or the Input Management module 536. Thegestures may be as defined in conjunction with FIGS. 4A through 4H. Forexample, moving a window causes the display to render a series ofdisplay frames that illustrate the window moving. The gesture associatedwith such user interface interaction can be received and interpreted bythe Gesture Module 576. The information about the user gesture is thensent to the Task Management Module 540 to modify the display binding ofthe task.

The Requirements Module 580, similar to the Preferences Module 572, isoperable to determine display requirements for an application 564 orother component. An application can have a set display requirement thatmust be observed. Some applications require a particular displayorientation. For example, the application “Angry Birds” can only bedisplayed in landscape orientation. This type of display requirement canbe determined or received, by the Requirements Module 580. As theorientation of the device changes, the Requirements Module 580 canreassert the display requirements for the application 564. The DisplayConfiguration Module 568 can generate a display configuration that is inaccordance with the application display requirements, as provided by theRequirements Module 580.

The Event Module 584, similar to the Gesture Module 576, is operable todetermine one or more events occurring with an application or othercomponent that can affect the user interface. Thus, the Event Module 584can receive event information either from the event buffer 556 or theTask Management module 540. These events can change how the tasks arebound to the displays. The Event Module 584 can collect state changeinformation from other Framework 520 components and act upon that statechange information. In an example, when the phone is opened or closed orwhen an orientation change has occurred, a new message may be renderedin a secondary screen. The state change based on the event can bereceived and interpreted by the Event Module 584. The information aboutthe events then may be sent to the Display Configuration Module 568 tomodify the configuration of the display.

The Binding Module 588 is operable to bind the applications 564 or theother components to the configuration determined by the DisplayConfiguration Module 568. A binding associates, in memory, the displayconfiguration for each application with the display and mode of theapplication. Thus, the Binding Module 588 can associate an applicationwith a display configuration for the application (e.g. landscape,portrait, multi-screen, etc.). Then, the Binding Module 588 may assign adisplay identifier to the display. The display identifier associated theapplication with a particular display of the device 100. This binding isthen stored and provided to the Display Controller 544, the othercomponents of the OS 516, or other components to properly render thedisplay. The binding is dynamic and can change or be updated based onconfiguration changes associated with events, gestures, state changes,application preferences or requirements, etc.

User Interface Configurations:

With reference now to FIGS. 6A-J, various types of output configurationsmade possible by the device 100 will be described hereinafter.

FIGS. 6A and 6B depict two different output configurations of the device100 being in a first state. Specifically, FIG. 6A depicts the device 100being in a closed portrait state 304 where the data is displayed on theprimary screen 104. In this example, the device 100 displays data viathe touch sensitive display 110 in a first portrait configuration 604.As can be appreciated, the first portrait configuration 604 may onlydisplay a desktop or operating system home screen. Alternatively, one ormore windows may be presented in a portrait orientation while the device100 is displaying data in the first portrait configuration 604.

FIG. 6B depicts the device 100 still being in the closed portrait state304, but instead data is displayed on the secondary screen 108. In thisexample, the device 100 displays data via the touch sensitive display114 in a second portrait configuration 608.

It may be possible to display similar or different data in either thefirst or second portrait configuration 604, 608. It may also be possibleto transition between the first portrait configuration 604 and secondportrait configuration 608 by providing the device 100 a user gesture(e.g., a double tap gesture), a menu selection, or other means. Othersuitable gestures may also be employed to transition betweenconfigurations. Furthermore, it may also be possible to transition thedevice 100 from the first or second portrait configuration 604, 608 toany other configuration described herein depending upon which state thedevice 100 is moved.

An alternative output configuration may be accommodated by the device100 being in a second state. Specifically, FIG. 6C depicts a thirdportrait configuration where data is displayed simultaneously on boththe primary screen 104 and the secondary screen 108. The third portraitconfiguration may be referred to as a Dual-Portrait (PD) outputconfiguration. In the PD output configuration, the touch sensitivedisplay 110 of the primary screen 104 depicts data in the first portraitconfiguration 604 while the touch sensitive display 114 of the secondaryscreen 108 depicts data in the second portrait configuration 608. Thesimultaneous presentation of the first portrait configuration 604 andthe second portrait configuration 608 may occur when the device 100 isin an open portrait state 320. In this configuration, the device 100 maydisplay one application window in one display 110 or 114, twoapplication windows (one in each display 110 and 114), one applicationwindow and one desktop, or one desktop. Other configurations may bepossible. It should be appreciated that it may also be possible totransition the device 100 from the simultaneous display ofconfigurations 604, 608 to any other configuration described hereindepending upon which state the device 100 is moved. Furthermore, whilein this state, an application's display preference may place the deviceinto bilateral mode, in which both displays are active to displaydifferent windows in the same application. For example, a Cameraapplication may display a viewfinder and controls on one side, while theother side displays a mirrored preview that can be seen by the photosubjects. Games involving simultaneous play by two players may also takeadvantage of bilateral mode.

FIGS. 6D and 6E depicts two further output configurations of the device100 being in a third state. Specifically, FIG. 6D depicts the device 100being in a closed landscape state 340 where the data is displayed on theprimary screen 104. In this example, the device 100 displays data viathe touch sensitive display 110 in a first landscape configuration 612.Much like the other configurations described herein, the first landscapeconfiguration 612 may display a desktop, a home screen, one or morewindows displaying application data, or the like.

FIG. 6E depicts the device 100 still being in the closed landscape state340, but instead data is displayed on the secondary screen 108. In thisexample, the device 100 displays data via the touch sensitive display114 in a second landscape configuration 616. It may be possible todisplay similar or different data in either the first or second portraitconfiguration 612, 616. It may also be possible to transition betweenthe first landscape configuration 612 and second landscape configuration616 by providing the device 100 with one or both of a twist and tapgesture or a flip and slide gesture. Other suitable gestures may also beemployed to transition between configurations. Furthermore, it may alsobe possible to transition the device 100 from the first or secondlandscape configuration 612, 616 to any other configuration describedherein depending upon which state the device 100 is moved.

FIG. 6F depicts a third landscape configuration where data is displayedsimultaneously on both the primary screen 104 and the secondary screen108. The third landscape configuration may be referred to as aDual-Landscape (LD) output configuration. In the LD outputconfiguration, the touch sensitive display 110 of the primary screen 104depicts data in the first landscape configuration 612 while the touchsensitive display 114 of the secondary screen 108 depicts data in thesecond landscape configuration 616. The simultaneous presentation of thefirst landscape configuration 612 and the second landscape configuration616 may occur when the device 100 is in an open landscape state 340. Itshould be appreciated that it may also be possible to transition thedevice 100 from the simultaneous display of configurations 612, 616 toany other configuration described herein depending upon which state thedevice 100 is moved.

FIGS. 6G and 6H depict two views of a device 100 being in yet anotherstate. Specifically, the device 100 is depicted as being in an easelstate 312. FIG. 6G shows that a first easel output configuration 618 maybe displayed on the touch sensitive display 110. FIG. 6H shows that asecond easel output configuration 620 may be displayed on the touchsensitive display 114. The device 100 may be configured to depict eitherthe first easel output configuration 618 or the second easel outputconfiguration 620 individually. Alternatively, both the easel outputconfigurations 618, 620 may be presented simultaneously. In someembodiments, the easel output configurations 618, 620 may be similar oridentical to the landscape output configurations 612, 616. The device100 may also be configured to display one or both of the easel outputconfigurations 618, 620 while in a modified easel state 316. It shouldbe appreciated that simultaneous utilization of the easel outputconfigurations 618, 620 may facilitate two-person games (e.g.,Battleship®, chess, checkers, etc.), multi-user conferences where two ormore users share the same device 100, and other applications. As can beappreciated, it may also be possible to transition the device 100 fromthe display of one or both configurations 618, 620 to any otherconfiguration described herein depending upon which state the device 100is moved.

FIG. 6I depicts yet another output configuration that may beaccommodated while the device 100 is in an open portrait state 320.Specifically, the device 100 may be configured to present a singlecontinuous image across both touch sensitive displays 110, 114 in aportrait configuration referred to herein as a Portrait-Max (PMax)configuration 624. In this configuration, data (e.g., a single image,application, window, icon, video, etc.) may be split and displayedpartially on one of the touch sensitive displays while the other portionof the data is displayed on the other touch sensitive display. The Pmaxconfiguration 624 may facilitate a larger display and/or betterresolution for displaying a particular image on the device 100. Similarto other output configurations, it may be possible to transition thedevice 100 from the Pmax configuration 624 to any other outputconfiguration described herein depending upon which state the device 100is moved.

FIG. 6J depicts still another output configuration that may beaccommodated while the device 100 is in an open landscape state 348.Specifically, the device 100 may be configured to present a singlecontinuous image across both touch sensitive displays 110, 114 in alandscape configuration referred to herein as a Landscape-Max (LMax)configuration 628. In this configuration, data (e.g., a single image,application, window, icon, video, etc.) may be split and displayedpartially on one of the touch sensitive displays while the other portionof the data is displayed on the other touch sensitive display. The Lmaxconfiguration 628 may facilitate a larger display and/or betterresolution for displaying a particular image on the device 100. Similarto other output configurations, it may be possible to transition thedevice 100 from the Lmax configuration 628 to any other outputconfiguration described herein depending upon which state the device 100is moved.

FIG. 7A depicts a device 100 with first 104 and second 108 screens. Avirtual keyboard 704 is presented by the screens 104, 108. Inparticular, a first portion 704 a of the virtual keyboard 704 ispresented by a first portion 104 a of the first screen 104, while asecond portion 704 b of the virtual keyboard 704 is presented by a firstportion 108 a of the second screen 108. More particularly, the virtualkeyboard 704 spans a line of separation 708 between the first and secondscreens. Moreover, the virtual keyboard 704 does not occupy all of thearea of either the first screen 104 or the second screen 108.Accordingly, a second portion 104 b of the first screen 104 and a secondportion 108 b of the second screen 108 remain available for thepresentation of information other than the virtual keyboard 704 to auser. More particularly, in this example, a first application or window712 is displayed by a portion of the first screen 104, while a secondapplication or window 714, here comprising a desktop, is displayed by aportion of the second screen 108. In addition, the first application orwindow 712 has keyboard focus, as indicated by the input field 720. Asused herein, keyboard focus means that a virtual keyboard or other inputmeans is operable with respect to the application having the keyboardfocus, allowing a user to provide input to the application or thataffects the application through the virtual keyboard 704 or other input.

FIG. 7B depicts the output of the device 100 illustrated in FIG. 7A,after the launch of an application 716, presented by the second screen108. The original application 712 is presented by the first screen 104.In this example, the newly launched application 716, is not set toreceive keyboard focus on launch. Accordingly, launch of the application716 results in the dismissal of the keyboard 704. In addition, the inputfield 720 in the configuration illustrated in FIG. 7A can bediscontinued.

FIG. 8A depicts a device 100 on which a virtual keyboard 704 ispresented by first 104 and second 108 screens. A first application orwindow 712 is presented by the first screen 104, while a second window714, in this example a second desktop, is displayed by the second screen108. In FIG. 8B, the device 100 shown in FIG. 8A is illustrated, afterthe launch of an application set to receive keyboard focus on launch.Accordingly, as shown in FIG. 8B, the second screen 108 now displays anewly launched application or window 716, here Application 2. Inaddition, the virtual keyboard 704 continues to be displayed. Notably,whereas an input field 720 was presented in connection with the firstapplication 712 in the initial state illustrated in FIG. 8A, after thesecond application 716 is launched, the input field 720 is presented inconnection with the second application 716. Accordingly, by providinginstructions to present a virtual keyboard 704 on launch, the secondapplication 716 is ready to receive input from the user, withoutrequiring the user to take additional steps to call up the virtualkeyboard 704.

FIG. 9A depicts a device 100 in another exemplary scenario. In thisexample, a first application 712 is presented on a first screen 104, anda second window 714, here a desktop view, is presented by the secondscreen 108. No virtual keyboard is presented as part of the initialstate. In FIG. 9B, the device 100 illustrated in FIG. 9A is shown, aftera second application 716 has been launched that is set to receivekeyboard focus on launch. Accordingly, after the second application 716is launched, the device 100 displays a virtual keyboard 704. Moreover,an input field 720 can be presented in connection with the secondapplication 716. Accordingly, embodiments of the present inventionprovide for the presentation of a virtual keyboard 704 to enable a userto provide input upon the launch of an application 716, withoutrequiring any additional user input.

FIG. 10 depicts aspects of a method for providing a virtual keyboard onapplication launch or initiation in accordance with embodiments of thepresent invention. Initially, at step 1004, input is received to launchan application 712, 716. As an example, such input can be received asuser input, for example selecting an application to launch. As a furtherexample, input to launch an application can be received as aninstruction from another application, executed locally or remotely.

At step 1008, a determination is made as to whether the applicationbeing launched is set to receive keyboard focus on launch. If theapplication being launched is set to receive keyboard focus, adetermination can next be made as to whether a virtual keyboard 704 isalready being presented by the device 100 (step 1012). If a virtualkeyboard is already being presented, that virtual keyboard 704 cancontinue to be presented by the device 100, in addition to thepresentation of the application being launched (step 1016). If at step1012 it is determined that the virtual keyboard 704 is not already beingpresented, a virtual keyboard 704 can be presented, together with thelaunched application (step 1020).

If at step 1008 it is determined that the application being launched isnot set to receive keyboard focus on launch, a determination is made asto whether a virtual keyboard 704 is already being presented (step1024). If the virtual keyboard 704 is already being presented, thepresentation of the virtual keyboard 704 is discontinued (step 1028).After discontinuing the presentation of the virtual keyboard, or afterdetermining that a virtual keyboard is not already present, the launchedapplication is presented (step 1032). Accordingly, in connection withthe launch of an application that is not set to receive keyboard focus,no virtual keyboard 704 is displayed.

As can be appreciated by one of skill in the art after consideration ofthe present disclosure, embodiments of the present invention enable avirtual keyboard 704 to be presented or not, depending on settingsassociated with an application being launched. More particularly, wherethe application being launched is associated with an instruction placekeyboard focus on the application on launch, a virtual keyboard 704 caneither be generated and presented with the application being launched,or where a virtual keyboard 704 already exists, that existing virtualkeyboard 704 can be maintained when the launched application ispresented. Conversely, where an application being launched is notassociated with an instruction to associate a keyboard focus with theapplication, the launch of the application does not result in aconcurrent presentation of a virtual keyboard 704. In addition, where avirtual keyboard 704 is being presented at the time an instruction tolaunch an application that is not set to receive keyboard focus onlaunch is received, the presentation of that virtual keyboard 704 can bediscontinued upon the launch of the application. In accordance withembodiments of the present invention, the instructions to set keyboardfocus on an application (or not) on launch can be implemented in variousways. For example, such instructions can be provided as part of theexecutable code of the application, as a system setting, or as a scriptthat is executed upon the launch of the application.
